Black Obsidian Gua Sha Tool — Fish Shape, 5" x 2.5"

The black obsidian fish is the boldest and most striking tool in the gua sha collection — and at 5" long and 2.5" wide, it is also the most substantial. Larger than the jade fish, this tool covers more surface area with each stroke, making it well-suited to bodywork on the back, shoulders, and thighs, while the fish profile's curved spine, tapered nose, and notched tail still provide the versatility for detailed facial and neck work when needed.

Obsidian is volcanic glass — formed when lava cools rapidly, producing a material of extraordinary density and smoothness. Its surface is as close to frictionless as any natural material available, which translates directly into a gua sha experience that glides cleanly across oiled skin with minimal drag and consistent, even pressure. The weight and solidity of obsidian gives the tool excellent feedback in the hand and allows the practitioner or patient to work with less force than lighter tools require.

In Chinese medicine and classical Daoist practice, obsidian is considered a strongly grounding and consolidating material — associated with the Kidney system and the root of yang. Practically speaking, it is one of the most beautiful stones to work with: the deep, mirror-like black surface and the translucent quality of the polished edges make this as much an object of aesthetic pleasure as a clinical tool.

This is an excellent choice for patients who want a single, versatile gua sha tool that works equally well for whole-body treatment and facial refinement, or for anyone drawn to the visual and tactile qualities of volcanic stone.

Dimensions: Approximately 5" long x 2.5" wide Material: Natural black obsidian, polished smooth Best for: Back, shoulders, thighs, neck, jaw, facial contouring, full-body gua sha

Apply oil to skin before use. Each piece is natural obsidian and will vary slightly in surface character and translucency. Some surface redness following treatment is normal and typically resolves within 24–48 hours. Handle with care — obsidian is glass and will chip or break if dropped on hard surfaces. Consult your practitioner before beginning home gua sha treatment.
